Credit Card Form

Hi ya'll 👋. This is my solution to the credit cards form challenge. As usual, I threw a dark mode in there. And I tried to work harder on accessibility in this challenge. What I found troublesome was adding a border-gradient to the inputs. I had intended on using pseudo-elements, but they don't work. I later settled for border-image(which doesn't work with border-radius). I would like to know if there are other approaches to this.

Any comments on the code and how to better it would be greatly appreciated. Happy coding💻,
